    • Bloodborne Pathogens Kyle Schlarman Environmental Safety and Health Specialist Environmental Health and Safety Department Email: kschlar@bgsu.edu Phone: (419) 372-2173
    • Bloodborne Pathogens • Pathogenic organisms present in human blood that can cause disease in humans.* • Examples of bloodborne diseases: – Human Immunodeficiency Virus (HIV) – Hepatitis B – Hepatitis C *OSHA Definition
    • Potentially Infectious Bodily Fluids
    • Occupational Exposure Departments/Areas • Separation into two categories based upon risk – Category 1 – employees who, through the course of their delegated work activities, are reasonably expected to come into contact with blood or other potentially infectious material. – Category 2 – employees who may periodically or infrequently come into contact with blood or other potentially infectious material during the performance of their delegated work activities. • Dictates levels of protection, training, etc.
    • Universal Precautions Prevention Strategy: Assume all blood and other “potentially infectious materials” are infectious
    • How They are Spread • Accidental Puncture with contaminated needles, broken glass, or any other sharp object that can pierce skin • Contact between broken or damaged skin and infected bodily fluids • Exposure of infected bodily fluids to eyes, mouth, or nose • Indirect transmission such as touching a contaminated object to your eyes, mouth, or nose.
    • How does exposure occur?
    • The Big Three
    • Human Immunodeficiency Virus (HIV)
    • Some of the alarming facts of the HIV/AIDS tragedy worldwide: • • • • • • • Over 27 million AIDS-related deaths since 1980 42 million people are living with HIV/AIDS 3 million annual AIDS-related deaths Sub-Saharan Africa most affected Fast growing rates in China, India, Indonesia, Russia, Western Europe and Central Asia 25 million children will be orphans by 2010 because of AIDS
    • Some alarming facts of the HIV/AIDS tragedy in the USA • 1 million people in USA have HIV/AIDS • Approximately 11 of every 1,000 adults (ages 15 to 49) are HIV Infected 24-27% undiagnosed and unaware of their HIV infection • Women are the fastest growing group to be infected with HIV
    • Human Immunodeficiency Virus (HIV) • HIV is the virus that leads to AIDS • HIV depletes the immune system • HIV does not survive well outside the body • There is still no vaccine available NOT spread by saliva, sweat, spit, tears • HIV is spread when infected blood, semen, vaginal fluids, or breast milk gets into the bloodstream: Transmission rate thru exposure 0.3% – Sexual contact – Sharing needles – Pregnancy, childbirth and breastfeeding • Workplace exposure to blood/ body fluids
    • Symptoms of HIV Infection • May have some “flu-like” symptoms within a month after exposure – Fevers, chills, night sweats and rashes, sore muscles and joints, swollen lymph glands – 7 – 10 years later symptoms appear – Skin rashes, fatigue, slight weight loss, night sweats, chronic diarrhea, thrush in the mouth • Symptoms last more than a few days and may continue for several weeks
    • Acquired Immunodeficiency Syndrome (AIDS)
    • AIDS • Development of opportunistic infections that do not usually infect people with a healthy immune system • The signs and symptoms depend on the type of infection – – – – – Swollen lymph glands in the neck, underarm, and groin area Recurrent fever Persistent headaches and night sweats Constant fatigue Persistent diarrhea • Without treatment, a person could die from a simple infection. • Treatment does not cure the infection • Treatment delays the progression of AIDS and improves the quality of life
    • Most Common Opportunistic Infections
    • Hepatitis B Virus (HBV)
    • Hepatitis B (HBV) • • • • • A virus that infects the liver HBV can survive outside the body at room temperature for over 7 Days HVB is more easily spread than HIV 90% of adults contracting the disease recover fully and develop immunity Up to 10% of adults contracting the disease become carriers Transmission rate thru exposure 33% 100X More Infectious than HIV • Infected blood and body fluids • In infected persons, HBV can be found in: – Blood, Body tissue, Saliva, Semen – Vaginal secretions, Urine, Breast milk • • Puncture wounds from sharps Contaminated body fluids entering: – An opening or break in the skin – Splashing into mucous membranes – eyes, nose, mouth • Unprotected sex, Intravenous drug use, Blood transfusions
    • Symptoms of HBV Infection • • • • • • • • • Flu-like illness Aches Fatigue Nausea Vomiting Loss of appetite Abdominal pain Occasional diarrhea Jaundice • Vaccine • A non-infectious, yeastbased vaccine • Prepared from recombinant yeast cultures, not from human blood products • No risk of developing HBV disease from the vaccine • The vaccine has been proven to be 90%+ effective
    • Hepatitis B Vaccine • The vaccine is given in a three dose series – Dose #1 – Initial dose – Dose #2 – 30 days after dose #1 – Dose #3 – 4 months after dose #2 • The vaccine is administered in the deltoid muscle in the upper arm All 3 vaccines needed for immunity
    • Side Effects of the Hepatitis B Vaccine • • The vaccine is usually well tolerated. If side effects are experienced, contact: – Your medical provider • Vaccine Adverse Event Reporting System (VAERS) 800-822-7967 or http://www.vaers.org • Do not take the vaccine if: – You are allergic to yeast – You are pregnant or planning to become pregnant within the year – You are ill (cold, flu, or on medication) on your appointment date – You are in doubt due to other medical issues, concerns or complications (see your Physician)
    • Hepatitis C Virus (HCV)
    • General Facts About Hepatitis C • • • • • HCV was identified in 1989 One of the most common causes of chronic liver disease, cirrhosis and cancer ~ four million people affected in USA – with 180,000 new infections annually 8,000-10,000 HCV annual deaths in USA Globally ~ 170 million chronic infections
    • Hepatitis C Worldwide • Most commonly occurs in people who have: – received blood transfusions before 1992 – shared needles – had tattoos – had body piercing • • • Risk of sexual transmission appears to be small No evidence that it can be transmitted by casual contact, through foods, or by coughing or sneezing Transmission from mother to child appears to be uncommon • • • • • The virus is very robust. The virus can remain undetected in the body for years HCV may be identified after 5 - 8 weeks from exposure in approximately 60% of infected persons Most Hepatitis C infections (8090%) become chronic and lead to liver disease and liver failure There is no vaccine for Hepatitis C Transmission rate thru exposure 3%
    • Sources of Infection for Persons with Hepatitis C - USA • • • • • • • SYMPTOMS Appetite loss Fatigue Nausea Vomiting Vague stomach pain Muscle and joint pain Jaundice (yellowing of skin, yellowing of the whites of the eyes, dark urine)
    • RATIONALE FOR THE BLOODBORNE PATHOGENS STANDARD
    • Bloodborne Pathogens Standard • Occupational Exposure to Bloodborne Pathogens • 29 CFR 1910.1030 • Published December, 1991 • Effective March, 1992 • Established under the provisions of the Ohio Public Employment Risk Reduction Program – OSHA Bloodborne Pathogen Standard • Public Employee Risk Reduction Program
    • Rationale for the Bloodborne Pathogens Standard • • • • ~ 8,700 healthcare workers are infected with Hepatitis B each year. One milliliter of blood can contain over 100,000,000 infectious doses of Hepatitis B virus. OSHA estimates approximately 8 million health care workers and related industries have exposure to bloodborne pathogens ~ 65 cases of HIV infection due to occupational exposure occur each year
    • Bloodborne Pathogens Standard • • The OSHA Bloodborne Pathogen Standard applies to all occupational exposure to blood or other potentially infectious materials. Example: blood or body fluids splashed onto clothing or body Report any exposure incidents to your Environmental Health & Safety Office as soon as possible • Exposure Control Plan
    • Components of the BGSU Exposure Control Plan (ECP) • Exposure Control • Employee Exposure Determinations • Methods of Compliance – a. Universal Precautions – b. Engineering & Work Practice Controls – c. Personal Protective Equipment – d. Housekeeping – e. Labeling • Hepatitis B Vaccination • Post-exposure Evaluation and Followup • Communication of Hazards To Employees and Training • Recordkeeping
    • Exposure Control
    • Engineering Controls • These are methods to reduce employee exposure by isolating the hazard. Examples: – Sharps disposal containers – Self-sheathing needles – Safer medical devices – Needle less systems – Sharps with engineered sharps injury protections •Contaminated needles and/or sharps must not be bent or Recapped •Contaminated sharps must be placed in appropriate containers as soon as possible after use. •Readily available hand washing facilities
    • Engineering Controls
    • Wash Hands • When visibly contaiminated • After using the washroom • After removing gloves • After blowing your nose • After sneezing in your hands • Before and after eating, handling food, drinking or smoking • Before and after assisting a child in using the toilet • After diaper changes • After contact with runny noses, vomit, or saliva • Before feeding children • After handling pets, animals or animal waste • After handling garbage
    • Technique for Hand washing • Remove rings and watches before washing • If hands-free dispenser is not available, dispense paper towels before washing • Hand should be positioned lower than the arms to avoid contamination 1. Use soap and running water 2. Rub your hands vigorously for 10 – 15 seconds 3. Wash all surfaces: • Backs of hands, wrists, between fingers and under nails 4. Rinse well 5. Dry hands with a disposable towel
    • Work Practice Controls • Controls aimed at reducing or minimizing the employee’s exposure to blood and body fluids • EXAMPLES • Covering all open skin lesions • Minimizing the splashing, splattering, spraying or generation of droplets of blood or body fluids • Wash hands and body parts after contact with blood and body fluids • Decontaminating equipment and surfaces • Forbidding eating, drinking, after contact with blood and body fluids
    • General Workplace Guidelines • Housekeeping • Never reach into contaminated sharps disposal containers • Place regulated waste in closable and labeled or color-coded containers • Use labels and sign to communicate hazards • Use mechanical means, brush and dust pan, tongs to pick up broken glassware • Remove and replace protective coverings when contaminated • Discard all regulated waste according to regulations
    • Decontamination • All equipment and work surfaces must be cleaned and decontaminated with an EPA approved disinfectant after: – Contact with blood or OPIM – After completion of procedures and after any spills of blood or OPIM • Use appropriate PPE • Wipe small amounts of infectious material with paper towels • Dispose of body fluids not visibly contaminated with blood in regular garbage
    • Decontamination Procedures • Absorb blood with absorbent materials and place in a tied, doubled red bag. • Use an acceptable commercial disinfectant for surfaces not contaminated with blood • Decontaminate mop, broom or dust pan in a bleach solution • Waste disposal/Laundry
    • Personal Protective Equipment (PPE) • PPE provides protection against exposure to infectious materials and must be routinely used when contact with blood or body fluids is anticipated. • Selection of PPE is task oriented. • Under normal conditions it prevents blood and body fluids from reaching an employee’s: – work clothes, street clothes, undergarments – skin, mouth, eyes, other mucus membranes
    • Communication of Hazards to Employees & Training
    • Labeling • • Labels must be fluorescent orange or orange-red with the biohazard symbol or biohazardous waste lettering in a contrasting color Individual containers of blood or OPIM that are placed in a labeled container during storage, transport, shipment or disposal are exempt from the labeling requirements
    • Training • Must be done annually for returning employees and new hires • Attendance sheet must be kept on file for 3 years • All employees who are assigned to tasks where occupational exposure may take place must be provided with information and training at the time of initial assignment • Training must include Q&A
    • Vaccines
    • Hepatitis B Vaccination Notification Form • • The vaccine is: – Free – Given on the employer’s time – Administered on-site The vaccine will only be given to those: – Who have been trained – Completed a Vaccination Notification form or Vaccination Declination form • The vaccine is offered to employees who have occupational exposure to bloodborne pathogens
    • Hepatitis B Forms Notification Form Declination Form • • States that the at-risk employee declines to take the vaccine at this time • The employee may opt to take the vaccine at a later date • Filled out by those in the Occupational Exposure Group • This form is a medical record. Must be retained • • Ensures the employee is aware of job related exposure risks Completed by at-risk employees who wish to take the Hepatitis B vaccine for the first time Site Administrator collects completed forms
    • Post Exposure Follow Up and Care
    • Post Exposure Procedure • • • If you have been contaminated by blood, you may have been exposed to Hepatitis B, Hepatitis C, and/or HIV. Wash off the exposed area immediately. Report the incident to your Manager in order to receive proper post-exposure evaluation and follow-up. • • • Employees must seek medical attention immediately. The doctor’s visit is free of charge. The employee reserves the right to decline medical attention – The employee must provide the reason for the declination in writing – A record of this declination must be kept on file
    • Post Exposure & Follow-up Policy • Employer must keep an accurate record for each employee with occupational exposure • Exposure Incident Report Log, Sharps Report Determine whether the case is recordable and/or reportable, Log and Summary of Occupational Injury and Illnesses form • If the case is recordable, then it must be recorded as a privacy case, and the employee’s name must be omitted from all OSHA forms.
    • Post Exposure & Follow-up Policy • Medical expenses incurred because of an exposure incident are covered by the employer • Forms and supporting documentation must be submitted to Risk Management. • Your Manager will be able to assist you in filing the appropriate forms.
    • Record Keeping Requirements
    • THE END
